Organizations are at a critical juncture in knowledge discovery – there’s a tremendous need to uncover meaning buried inside of unstructured data. Text mining is one technique used to uncover this intelligence. But where is this newly found knowledge stored, updated and queried?

GraphDB™ is the world’s leading RDF Triplestore built on OWL (Ontology Web Language) standards. It stores your data in the form of atomic facts expressed as subjects, predicates and objects which have relationships to other facts. Ontotext offers three versions: GraphDB™ Lite, GraphDB™ Standard and GraphDB™ Enterprise. Learn more about their unique features below.

GraphDB™

GraphDB™ is the world’s leading RDF Triplestore. It’s the only triplestore that can perform semantic inferencing at scale allowing users to create new semantic facts from existing facts. GraphDB handles massive loads, queries and inferencing in real time. We offer three versions of GraphDB™: Lite, Standard and Enterprise. Click into any edition to compare the differences between the three.

In essence, GraphDB™ is a “semantic repository” using ontologies that allow the repository to automatically reason about the data. It works with a flexible and generic physical graph data model allowing for easy interpretation and adoption of new ontologies or metadata on-the-fly. Sesame is one of the most popular semantic repositories that supports RDF(S) and all the major syntaxes and query languages related to it. GraphDB™ is another semantic repository, packaged as a storage and inference layer (SAIL) for Sesame. To learn more about Semantic Repositories, visit our page on the topic: Semantic Repositories.

GraphDB™ Lite

For those users interested in managing millions of RDF statements on a desktop computer, GraphDB™ Lite is a database management system licensed free of charge including inferencing and query support. This version does not allow users to load more than 100 million triples and performs query and reasoning operations in memory rather than files based indexing.

GraphDB™ Standard

With “Standard” users can load billions of RDF statements with inferencing and multi-user query performance. We have optimized the performance of the Standard Edition using “Same As” technology. This allows you to recognize when two different entities across different data sources actually refer to the same entity. With GraphDB™ Standard you can:

Load, query and infer new facts simultaneously

Run against tens of billions of RDF statements on a single server using file based indices

GraphDB™ Enterprise

GraphDB™ Enterprise has all the features of our Standard Edition with the added advantage that it has been architected to run on enterprise replication clusters with backup, recovery and fail over ensuring you are always up. “Enterprise” offers industrial strength resilience and linearly scalable parallel query performance with support for load-balancing across any number of servers.
